    Compression Lugs

    Image of Product. Front orientation. Terminals, Ferrules, and Lugs. Compression Lugs, Straight.

    Straight

    These lugs connect wire as large as 500 MCM in industrial feeder circuits, high-power service entrances, and other large systems. Squeeze the barrel tightly and evenly onto the wire with a compression tool for a permanent connection that stands up to heavy vibration, sudden shocks, and daily wear and tear. Compression lugs are a step up from set screw lugs when you need a physically strong connection, though set screw lugs attach to even larger wire.
    Single Crimp—Provides a secure enough grip for most jobs.

    These lugs attach to even larger wire than compression lugs, such as the 1000 MCM building wire used in large factories. They're also easier to install and reusable because you cinch the wire with a set screw rather than crushing the barrel. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.

    Connect multiple wires to a single lug. The stacked design takes up less lateral space than our other lugs for multiple wires, where the holes are arranged side to side.
    Set screw lugs attach to even larger wire than compression lugs, such as the 750 MCM building wire used in large factories. They're also easier to install and reusable because you cinch the wire with a set screw rather than crushing the barrel. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.

    Install these lugs in outdoor utilities, public buildings, and anywhere else you need to leave your installation unmonitored. Use an L-key to tighten the set screws onto the wire. When you apply enough torque, the screw heads shear off so the connection can’t be removed or altered.
    Set screw lugs attach to even larger wire than compression lugs, such as the 1000 MCM building wire used in large factories. They're also easier to install and reusable because you cinch the wire with a set screw rather than crushing the barrel.

    Set Screw Lug Assortments for Transformers

    Image of Product. Front orientation. Terminals, Ferrules, and Lugs. Set Screw Lug Assortments for Transformers.
    These assortments include the set screw lugs, nuts, and bolts needed for single-phase and three-phase dry-type transformers (transformers that dissipate heat without using liquid).
    Set screw lugs are easier to install than compression lugs, and they can be reused because you don't crush the barrel to attach the wire. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.

    Connect ground wire for transformers, control panels, and other electrical distribution components without cutting and splicing. Unlike other lugs, these attach in the middle of a run of wire, not the end—just lay the stripped wire into the lug and tighten the set screw.

    These lugs are designed to slide onto grounding or neutral bars in electrical panels. They're often relied on for control panel connections, where a secure hold on the wire helps prevent loose connections, overheating, and other interruptions. To install, insert your wire then clamp it down with the set screw onto the metal bar.
